I’ve always loved how a simple pot of greens can turn into something so nourishing and delicious. This spinach soup recipe has become one of my go-to meals when I want something healthy, comforting, and ready in about 30 minutes.
Fresh spinach melts into a creamy, velvety base that’s surprisingly rich without being heavy. The bright green color alone makes you feel like you’re doing something good for your body.
I first started making this when I needed to use up bags of spinach before they wilted. What began as a “clean out the fridge” moment has turned into a weekly staple in our home.
The best part? You can adjust the consistency to your liking—thick and hearty or light and brothy. Either way, it’s packed with nutrients and flavor that’ll make you forget you’re eating something so healthy.

The ingredient list is refreshingly short. You probably have most of these items in your kitchen already, which is part of what makes this recipe so convenient for last-minute meals.
- 10 ounces fresh spinach (or 16 ounces frozen spinach, thawed and drained)
- 2 tablespoons butter or olive oil
- 1 medium onion, diced
- 3 cloves garlic, minced
- 3 tablespoons all-purpose flour (or cornstarch for gluten-free)
- 4 cups vegetable broth (or chicken broth)
- 1 cup heavy cream (or coconut milk for dairy-free)
- 1/4 teaspoon nutmeg, freshly grated
- Salt and black pepper, to taste
- 1/2 teaspoon red pepper flakes (optional, for a subtle kick)
- 1 tablespoon lemon juice (brightens the flavors)

Recommended Products for This Recipe
I’ve tested this recipe with various products over the years, and these specific items have made a noticeable difference in both the cooking process and final result. They’re investments that’ll serve you well beyond just this soup.
1. Vitamix Immersion Blender
The Vitamix immersion blender creates the silkiest texture without having to transfer hot soup to a countertop blender. The variable speed control lets you choose your preferred consistency, from slightly chunky to completely smooth.
2. Le Creuset Dutch Oven
A Le Creuset enameled cast iron Dutch oven distributes heat evenly, preventing any scorching on the bottom while you’re building the soup base. The 5.5-quart size is perfect for making enough soup to feed a family with leftovers.
3. Organic Baby Spinach
I consistently reach for organic baby spinach because the leaves are tender, pre-washed, and have a sweeter, less bitter flavor than mature spinach. Fresh, high-quality greens make all the difference in the final taste.
4. Pacific Foods Organic Vegetable Broth
Pacific Foods organic vegetable broth has a clean, well-balanced flavor that enhances the spinach without overpowering it. Unlike some broths that taste overly salty or artificial, this one adds genuine depth to the soup.
Step-by-Step Instructions
These detailed instructions will walk you through every stage of making perfect spinach soup. Take your time with each step, and you’ll end up with restaurant-quality results at home.
1. Prepare Your Ingredients
- Wash fresh spinach thoroughly in a large bowl of cold water, swirling it around to remove any grit or dirt
- Lift the spinach out of the water and shake off excess moisture (don’t worry about drying it completely)
- If using frozen spinach, thaw it completely and squeeze out as much liquid as possible using your hands or a clean kitchen towel
- Dice the onion into small, uniform pieces (about 1/4-inch)
- Mince the garlic cloves finely, or use a garlic press for convenience
- Measure out all other ingredients and have them ready near your cooking area
2. Sauté the Aromatics
- Heat the butter or olive oil in your large pot or Dutch oven over medium heat until the butter melts and begins to foam
- Add the diced onion and cook for 5-7 minutes, stirring occasionally, until the onion becomes translucent and soft but not browned
- Add the minced garlic and cook for another 60-90 seconds, stirring constantly to prevent burning
- The aromatics should smell fragrant and sweet, signaling they’re ready for the next step
3. Create the Roux
- Sprinkle the flour evenly over the sautéed onion and garlic mixture
- Stir constantly with a wooden spoon for 2-3 minutes, ensuring the flour is fully incorporated and cooking out the raw flour taste
- The mixture should form a thick paste and begin to turn a light golden color
- This roux will help thicken your soup and give it a velvety texture
4. Add the Broth
- Slowly pour in the vegetable or chicken broth while stirring continuously to prevent lumps from forming
- Start with just 1 cup of broth and stir vigorously until smooth, then gradually add the remaining broth
- Increase the heat to medium-high and bring the mixture to a gentle simmer
- Continue stirring occasionally to ensure the roux is fully dissolved into the broth
5. Cook the Spinach
- Add the fresh spinach to the pot in batches if necessary (it will wilt down significantly)
- If using frozen spinach, add it all at once since it’s already compacted
- Stir the spinach into the hot broth until it’s completely wilted and incorporated (this takes about 2-3 minutes for fresh, 1 minute for frozen)
- Reduce the heat to medium-low and let the soup simmer for 5 minutes to allow the flavors to meld
6. Blend the Soup
- Remove the pot from the heat and let it cool for 2-3 minutes (this prevents dangerous splattering)
- Use an immersion blender to puree the soup directly in the pot, blending until smooth and creamy (about 1-2 minutes)
- Alternatively, carefully transfer the soup in batches to a countertop blender, filling it only halfway each time and venting the lid
- Blend until you reach your desired consistency (completely smooth or with some texture remaining)
- Return the blended soup to the pot if using a countertop blender
7. Add Cream and Seasonings
- Place the pot back on low heat and stir in the heavy cream or coconut milk until well combined
- Add the nutmeg, salt, black pepper, and red pepper flakes (if using)
- Stir in the lemon juice, which brightens all the flavors and adds a subtle tang
- Taste the soup and adjust seasonings as needed (you may want more salt, pepper, or lemon juice)
- Let the soup heat through for 3-5 minutes, but don’t let it boil once the cream is added
8. Finish and Serve
- Remove the pot from heat and stir in the grated Parmesan cheese if using (it will melt into the soup beautifully)
- Ladle the hot soup into bowls immediately
- Garnish with extra Parmesan, a drizzle of cream, fresh cracked pepper, or a few fresh spinach leaves
- Serve alongside crusty bread, crackers, or a simple salad for a complete meal
Tips for Success
These practical tips come from making this soup dozens of times. They’ll help you avoid common pitfalls and ensure your spinach soup turns out perfectly every time.
- Don’t skip salting the soup progressively: Add salt at multiple stages (when sautéing onions, after adding broth, and after blending) for the most developed flavor
- Use fresh nutmeg if possible: Pre-ground nutmeg loses its potency quickly, while freshly grated nutmeg adds a warm, aromatic quality that’s incomparable
- Control the thickness: If your soup is too thick, thin it with additional broth or water; if it’s too thin, simmer it uncovered for 5-10 minutes to reduce
- Be careful with the blender: Hot liquids expand when blended, so always vent your blender lid and start on low speed to prevent accidents
- Taste before serving: Spinach can vary in bitterness depending on the season and variety, so you may need to adjust the lemon juice or add a pinch of sugar
- Fresh vs. frozen spinach: Frozen spinach has a more concentrated flavor and requires less volume, but fresh spinach gives a brighter, more vibrant color
- Prevent skin formation: If not serving immediately, place plastic wrap directly on the surface of the soup to prevent a skin from forming

Serving Suggestions
This versatile soup pairs beautifully with both simple and elaborate accompaniments. The mild, creamy flavor complements a wide range of side dishes and toppings.
Consider serving your spinach soup with crusty sourdough bread, garlic bread, or homemade croutons for dipping. A grilled cheese sandwich makes it feel like the ultimate comfort meal combo.
For toppings and garnishes:
- Crème fraîche or sour cream swirled on top
- Crispy bacon bits for a smoky, savory contrast
- Toasted pine nuts or slivered almonds for crunch
- Fresh herbs like chives, parsley, or dill
- A poached or soft-boiled egg nestled in the center
- Crumbled feta or goat cheese for tang
- Homemade croutons or crispy chickpeas
This soup also works wonderfully as a starter before serving baked salmon or roasted potatoes.
Variations to Try
Once you’ve mastered the basic recipe, these variations let you customize the soup to your taste preferences or dietary needs. Each one brings a completely different character to the dish.
- Spinach and white bean soup: Add one 15-ounce can of drained white beans before blending for extra protein and a heartier texture
- Thai-inspired version: Replace cream with coconut milk, add fresh ginger and lemongrass, and finish with lime juice and cilantro

Frequently Asked Questions
1. Can I use baby spinach instead of regular spinach?
Absolutely! Baby spinach actually works beautifully in this recipe and is often more convenient since it comes pre-washed. You’ll get a slightly sweeter, milder flavor compared to mature spinach, and the tender leaves blend into an incredibly smooth, velvety texture. Use the same amount by weight (10 ounces), though it might look like more volume since baby leaves are smaller.
2. Why did my soup turn brown instead of staying bright green?
Spinach soup can lose its vibrant color if it’s cooked too long or at too high a temperature. To keep it bright green, add the spinach toward the end of cooking and simmer gently rather than boiling vigorously. Adding the lemon juice at the end also helps preserve the color, and blending the soup while it’s still hot (but not boiling) maintains that beautiful green hue.
3. Can I make this soup without cream?
Yes, and you have several options! For a lighter version, simply skip the cream and use extra broth—the soup will be thinner but still flavorful. For a dairy-free creamy texture, use full-fat coconut milk, cashew cream (blend soaked cashews with water), or oat milk. You can also puree some cooked white beans or potatoes into the soup for natural creaminess without any dairy.
4. My soup tastes bitter—what went wrong?
Spinach can sometimes taste bitter, especially if it’s older or was grown in very hot weather. To fix bitter soup, add a small pinch of sugar (1/4 to 1/2 teaspoon) to balance the flavors. Increasing the lemon juice, adding more cream, or stirring in a bit of Parmesan cheese can also mask bitterness. Next time, taste your raw spinach first and choose the freshest, sweetest-tasting leaves you can find.
5. How do I make this soup thicker or thinner?
To thicken the soup, simmer it uncovered for 10-15 minutes to reduce the liquid, or add a slurry made from 1 tablespoon cornstarch mixed with 2 tablespoons cold water. You can also blend in a peeled, cooked potato or add more roux (equal parts butter and flour cooked together). To thin it out, simply stir in additional broth, water, or cream until you reach your desired consistency.
